PIN
FUNCTION
Control input pin. Forcing this pin above 1.5V enables APW7101. Forcing this pin below 0.3V shuts
1
RUN
down APW7101. In shutdown situation, all functions are disabled to decrease the supply current
below 1µA.There is no pull high or pull low ability inside.
2
GND
Ground pin.
3
SW
Connected this pin to the inductor of the power stage. This pin connected to the drain terminals of
the main and synchronous power MOSFET switches inside.
4
VIN
Must be closely decoupled to GND with 4.7µF or greater ceramic capacitor.
In the adjustable version, feedback function is available. The feedback voltage decided by an
5
VFB/VOUT external resistive divider across the output. In the fixed version, an internal resistive divider divides
the output voltage down for comparison to the internal reference voltage.
